Yes. For safety certifications, Lithium Ion batteries present a risk that needs to be considered. If the batteries are short-circuited, overcharged, or charged (if not rechargeable) there is a potential for fire. If you are using UL Recognized batteries, you can use the maximum reverse charging/overcurrent ratings in designing your protection circuit. Remember to use two layers of protection, to protect in case of a single fault. Note there are batteries on the market which incorporate this protection. The batteries themselves need to meet UN testing requirements for transport (testing is primarily environmental), and in the US, the DOT is supposed to be adopting the UN standard soon to be required for battery transport in the US. There are exceptions, but primarily for very small batteries. This requirement is intended for the battery manufacturer, not the end user. If you have any more questions, feel free to ask me directly. Thanks, Sam Davis Product Safety Certifications Engineer Professional Testing Inc.

Are there any approvals issues that may need to be re-considered e.g. EMC, Safety, battery approval reqts..... or? As always I look forward to your expert opinions.
